NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 280,125, dated June 26, 1883.

Application filed October 25, 1882.

at Canton, in the county of Stark and State oi'v Ohio, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

. Figure lis a side elevation oi' one form of my improved nut-locking device. Fig. 2 is a central longitudinal section of the same. Fi 3 and 4 represent. modied forms of myuiutlock.

In the drawings', A represents the bolt, having the head B and screw-threaded portion a,

upon which the nut E travels. I have shown the nut formed with recesses e upon its outer tace, though some of the advantages of my i11- vention may be attained even though this i'aee of the nut be made i'lat and smooth.

G represents a locking-piece of substantially the same shape as the nutE. Upon its inner tace it is provided with lugs g, 4corresponding in position with the recesses in the face of nut E, and adapted to enter the recesses, and thus aid in locking the nut in place. This lockingpiece is formed with a central recess, H, which passes over but does not engage with the bolt A, thus permitting the part G to engage with the nut E, even though the latter be screwed a considerable distance upon the bolt.

I represents a clamping-piece carried by a bolt, F, of less diameter than the bolt A, and adapted to hold or clamp the part G tightly in place against the outer face ofthe nut.

In the construction shown in Figs. 1 and 2 the bolt A is provided with a longitudinal hole, D, extending its entire length. Passing through this hole is a stem or bolt, which at one end is connected, either by screw-thread or by `being formed integrally therewith', with the locking part G, and at the otherend is provided with a screw-thread, 7". I preferably make the pitch and direction of the threads on bolt F different from those at e on bolt A. Engaging with the threaded part of bolt F is the clamping part or nut I, which, when the parts are locked in position, bears against the head of bolt rA.

The means for iastening the recessed locking part G may be slightly modified, as shown in Figs. and +L. In Fig. S the interior longi- (No model.)

tudinal hole, D, is scrcw-threaded, and the reduced bolt or rod F is threaded to engage therewith, and carries the expanded clamping part or head I, which bears against the outer face of the part G, thus clamping it iirmly against the nut E. In this construeti onthe lock G is of the forni of a shell passing over the bolt A, and has a hole through which the bolt F passes. In the construction shown in Fig. Li the reduced bolt or rod F is formed integrally with the bolt A, projecting from the end thereof. t It is provided with a screw-thread opposite to that on the bolt A, adapted to engage with and carry the clamping-nut I, by which the part G can be clamped tightly in place.

VIn the drawings I have shown the hole D as being formed centrally, though some of the purposes of my invention may be attained il" this hole be somewhat eccentric.

By having the clamping part which holds the lock G against the outer face of the nut move on lines .parallel with the movement ot the nut, I am enabled to lock the nut E lat alA most any desired point on the bolt A, even though it be in such positionMas, for instance,

in a countersunkrecess-that a pin, key, or locking-bolt cannot be passed through said body on a line transverse to the bolt, or when the nuthis in such position that the ilanges oi' the lock cannot be passed down bythe side oi' the nut E, hence my invention possesses advantages over any other nut-lock oli which I have knowledge.'

that I claimisl. In combination with the bolt A and nut E, the lock G, situated, as described, entirely outside ot' the nut l, and adapted io bear against the outer face of the nut, and having a central recess adapted to pass over the belt, but not engage therewith, a threaded bolt oi less diameter than the bolt A, and amovable clamping part, I, which, by means of the thread on the reduced bolt, clamps together the lock, the bolt, andthe nut, substantially as set i'orth.

2. In combination with the bolt A and nut (E, traveling thereon, the lock G, adapted to IOO clamp the lool; against the nut, substantially as set forth.

3. The combination of nut E, Jdie look G,

- having` a eentral reeess adapted to pass over the bolt A, but not engage therewith, and adapted to bear against the outer face of the nut, the bolt A, provided with an internal longitudinal hole, and the Clamping part I, earried by a screw-threaded bolt, F, of reduced diameter, which enters the hole in the bolt, by which bolt F and part I the nut, lock, and bolt A are clamped together, substantially as set forth.

4L. In a nut-lock, a bolt having a hole exP` outer faee of the nut, a screw-threaded stem passing through the bolt and eonneeted with 2o the look, and a nut engaging with the serewthreaded stem and bearing against the head of the bolt, substantially as set forth.

5. The Combination, with the bolt A, having the screw-threaded portion a and the hole 25 D, of the nut E, provided with recesses e, the lock G, having lugs which engage with said recesses c, the stem or bolt F, attached to said lookv and passing through the hole D, and the nut l, substantially as set forth. 3o

In testimony whereof I aiiix my signature in presenee of two witnesses.
